I got 100 cornish chicks 4 weeks ago. I have lost 20 + chicks. They have food all day and I take it way @ night. I have heat lamp on them. They all look good and running a round and then the next morning there will be 4-5 dead. Then I will go a week without any dying. Is it the breed or what? I've heard they will mash each other and they are not the brightest. I don't understand.
